The 36-minute clip shows drummer Lars Ulrich meeting fans, the warm-up session prior to the band hitting the stage, their photoshoot with Ross Halfin and live footage from the band's first live performance of 2016, including their track Master Of Puppets.
Video screens at the side of the stage declared: "Metallica, too heavy for halftime" after Coldplay, Bruno Mars and Beyonce got the nod to appear at the game itself. And frontman James Hetfield acknowledged that chances of them ever appearing at the sporting event were slim.
